'Ghost Hunters' promo offers peek at new beginnings

Grant Wilson is gone but the rest of the TAPS teams is still on the hunt for paranormal evidence. In the new promo for Ghost Hunters on the Syfy network - returning for season 8.5 on Sept. 5 - the team seems to take on some nasty entities who like to scratch.

Also, Tango mentions that "rules are changing," so what rules is he referring to? And who will step up to take Grant's place? Our bet is on Steve. Finally, did we catch a glimpse of a new female investigator?

Stay tuned for answers...
